Answer:In the United States, federal law normally governs the regulation of units of measure, including for electricity sold as fuel for electric vehicles. Through organizations like the National Institute of Standards and Technology (NIST), the U.S. federal government creates standards for units of measure and guarantees uniformity throughout the nation.
Step-by-step explanation:
Kilowatt-hour (kWh) is the most popular unit of measurement for electricity when discussing the charging of electric vehicles (EVs). A kilowatt-hour (kWh) measures the energy used by a device having a one-kilowatt power rating during one hour of operation. In the United States and many other nations, this device is generally regarded and utilized.
States may have some regulatory control over the infrastructure for charging electric vehicles, such as permitting, safety requirements, and rate structures, but they typically lack the jurisdiction to choose the unit of measurement for energy sold as gasoline. National standards and regulatory frameworks serve as a guide for the adoption and use of standard units of measure for electricity, including for EV charging.
For the most accurate and recent information, it is always essential to study the most recent federal and state rules connected to electric car charging. This is because legislation and standards can change over time.
